What are causes of hypoxia?
Hypoxia is a medical condition in which oxygen is no longer sufficiently reaching your cells. It can be caused in a number of ways: - If your airway is closed, such as when you're choking on food or you're drowning, your lack of breathing will cause hypoxia - Toxins in the blood, such as carbon monoxide, can prevent blood from absorbing oxygen - Stagnant hypoxia can result from high G-forces, such as when a fighter pilot pulls a turn or you go through a spiral in a roller coaster. This type of hypoxia specifically affects the brain - Severe bleeding can lead to hypoxia if there isn't enough blood to transport oxygen - Other medical conditions can cause your cells to prevent oxygen transport across the cell membrane. Genetic conditions are rare but poisons and toxins can cause this
Can hypoxia cause cell injury or death?
The consequence of hypoxia is entirely dependent on its intensity, duration, and also dependent on the age, gender, and health status of the victim. Our brain uses 20% of the oxygen we breathe, so I believe that the consequences of a prolonged and intense hypoxia may cause irreversible brain cells' damage, thus leading to a fatal outcome.

Which people are most likely to exhibit clubbing?
The most common cause of clubbing is lung cancer. It is also commonly caused by other lung/heart diseases like interstitial lung disease or really any disease that causes chronic hypoxia. Hypoxia is a word used to describe the lack of sufficient oxygen supply in the body. Clubbing is caused by lack of oxygen in the blood, so on a basic note, any disease that causes the blood to be depraved of enough oxygen can cause hypoxia. The people most likely to exhibit clubbing are people with lung cancer, as lung cancer is responsible for over 50% of the cases.

How can chronic hypoxia affect your body if you still smoke all the time?
My mom smokes and she has chronic Hypoxia . She will hardly ever wear her oxygen and she still smokes a whole intire carton of cigarettes less than two weeks . How can that affect your body and the hypoxia ? She also has copd and Emphazima and she has told me she was not going to quite smoking . I know that if you have emphazima you are killing yourself slowly cause you are closing your wind pipe ciculation . She has told me she did not care something was going to take her out of this world if it was than if would be her cigarettes.

How does the body know to increase ventilation rate during exercise?
The truth is that nobody really knows what causes the increase of ventilaion in exercise and keeps it close to metabolic rate. CO2 is a powerful stimulator of breathing and an increase of CO2 is produced by the body in exercise. This increase however is only found in the venous circulation where there are no chemoreceptors to detect it. All of the know chemoreceptors (aortic, carotid and central chemoreceptors) are found in the arterial side where there is relativly no fluctuation in the partial pressure of CO2. Furthermore, when the chemoreceptors are denervated breathing can still increase as normal. Other possible candidates that are involved in increasing breathing are, muscle chemoreceptors, efferencekopie, proprioreceptors, catecholamines, potassium levels...but all are either unlikley to be a cause or are impossible to measure (e.g. efferencekopie). So the textbooks will tell you that ventilation remains close to metabolic rate, but they dont say (beacuse they dont know) how it is kept close to metabolic rate. For further information on this look at works by Mike Parkes (university of Birmingham, united kingdom).
